It's a Rugrats musical! Watch the babies sing songs to Dil! See Phil and Lil sing "Trike That Is Not For You" (sung to the tune of "Bicycle Built For Two"). Watch Chuckie belt out "Pack Up Your Troubles"! Awe to Angelica's giddy rendition of "Toyland"! Hear Tommy Pickles as he fronts the doo-wop lounge band The Rugettes! It's musical fun for everyone! - Description from Klasky Csupo
Tommy, Chuckie, Phil, Lil and Angelica perform songs in order to teach Dil about music.
